The welding process using an electric arc developed between a flux covered electrode and the metal being welded is known as __________.

Correct Answer: Option B — shielded metal arc welding

Shielded Metal Arc Welding (SMAW), often called stick welding, uses an electric arc between a flux-covered consumable electrode and the workpiece. The flux coating decomposes to provide a shielding gas and slag, protecting the molten weld pool from atmospheric contamination, which is essential for high-quality marine structural repairs.
